Residences
Although he made frequent visits to Mount Merrion House, south of Dublin, Richard FitzWilliam lived mainly at FitzWilliam House in the parish of Richmond, Surrey, to the west of London, where he formed his large art collection. He bequeathed it to his heir George Herbert, 11th Earl of Pembroke, who renamed it "Pembroke House" and the site is now represented by "Pembroke Villas" 5 pairs of large semi-detached Victorian villas on the northeastern side of Richmond Green. FitzWilliam had inherited the estate from his mother Catherine Decker. John Macky in his Journey through England (1722 to 1723), described the Decker estate at Richmond as follows:
The longest, largest, and highest Hedge of Holly I ever saw, is in this garden, with several other Hedges of Ever-Greens, Visto’s cut through Woods, Grotto’s with Fountains, a fine Canal running up from the River. His Duckery, which is an oval Pond brick’d round, and his pretty Summer-House by it to drink a Bottle, his Stove-Houses, which are always kept in an equal heat for his Citrons, and other Indian Plants, with Gardeners brought from foreign Countries to manage them, are very curious and entertaining. The house is also very large a-la-modern, and neatly furnished after the Dutch way.
Richard Bradley in his General treatise of husbandry and gardening for the month of July (1723) described the estate as follows:
Tis not long since I was Eye-witness to several fruited Pine Apples at Sir Matthew Decker’s, at Richmond, about Forty in number; some ripening, and others in a promising condition; the least of which Fruit was above four Inches long, and some were as large as any I have seen brought from the West-Indies: I measured one near seven inches long in pure fruit, and near thirteen Inches about… I proceed to give an Account of the method now practis’d at Sir Matthew Decker’s at Richmond, for the production of this excellent Fruit, which Mr Henry Telende his judicious Gardener has render’d so easy and intelligible, that I hope to see the Ananas flourish for the future in many of our English Gardens, to see the honour of the Artist, and the Satisfaction and Pleasure of those who can afford to eat them.
